Tocopherols

Tocopherols (Vitamin E)

Vitamin E is a vitamin that is fat-soluble and comes with antioxidant properties. There are eight different forms in which vitamin E may exist:

Alpha tocopherol

Alpha tocotrienol

Beta tocopherol

Beta tocotrienol

Gamma tocopherol

Gamma tocotrienol

Delta tocopherol and

Delta tocotrienol

The most active form of vitamin E found in humans is the alpha-tocopherol, and it is for this reason that when daily allowance and dosing recommendations they are made, they are usually made in Alpha-Tocopherol Equivalents, or ATE. Vitamin E supplements may be found in synthetic or natural forms, the latter of which tends to be labeled with a “d,” such as in d-gamma-tocopherol. The synthetic forms, on the other hand, tend to be labeled with “dl,” such as in dl-alpha-tocopherol.

Treating Different Health Conditions

Vitamin E has often been proposed as part of a treatment or prevention plan for a number of different health conditions, usually due to its antioxidant properties.

However, outside of treating the rare vitamin E deficiency, there is no scientifically proven medicinal usage of the supplementation of vitamin E outside of maintaining the recommended dosage. Ongoing research is current, especially in treating heart disease and cancer.

There have been recent concerns associated with how safe it is to take high doses of vitamin E supplements. The idea has been proposed about whether there is an increased risk of bleeding, especially with those who are also taking aspiring, heparin, warfarin and other blood thinners, or in patients who are deficient in vitamin K.

Evidence that has recently come to light has come to light that taking high doses of vitamin E supplements might increase the risk of death from “all causes,” though a separate study said there was no increase towards mortality for women who supplemented vitamin E on a daily basis. Caution is warranted.

Dosing

The doses as provided in this section are based on research by scientists, traditional use, publications or expert opinion. There are many supplements and herbs that have not been fully tested, meaning the effectiveness and the safety of taking them are not necessarily proven. Some brands may differ in how they make their supplements, using other ingredients, even with its own brand. They may not apply to all sorts of products. Always read the product labels.

Dietary Sources

The following foods are known to contain vitamin E:

Eggs

Fortified cereals

Fruit

Green leafy vegetables

Meat

Nuts

Nut oils

Poultry

Vegetable oils

Argan oil

Olive oil

Wheat germ oil and

Whole grains

Cooking may destroy some of the vitamins.

Adults

It is believed that most adults within the United States already have a sufficient amount of vitamin E from their dietary sources. The recommended allowance for adults over the age of 14 years is 15 milligrams ATE. The recommended allowance for pregnant women of any age whatsoever is about 15 milligrams ATE of vitamin E per day, with breastfeeding women of any age whatsoever needing 19 milligrams per day.

Children

Children between the ages of one and three years is six milligrams ATE per day. For children between the ages of four and eight years is seven milligrams ATE per day. For children between the ages of nine and 13 years is 11 milligrams ATE per day. Anybody over the age of 14 years is to receive 15 milligrams ATE of vitamin E per day. Pregnant women of any age at all should receive 15 milligrams ATE per day, and those who are breastfeeding, regardless of the age, should obtain about 19 milligrams ATE of vitamin E per day. No amount has been approved for infants.

Safety

It is not the position of the United States Food and Drug Administration, or FDA, to approve the regulation of supplements and herbs. Therefore, the effects may vary, there is no guarantee for the purity or the safety of the products, and there is no guarantee about its strength.
For this reason, it is vital to always read the labels on the product. For those who suffer from a medical condition or are taking any other supplements, herbs or drugs, it is important to go see and consult with a qualified professional before taking on a new therapy. Also make sure to consult a doctor at once if experiencing any side effects.

Side Effects and Warnings

Evidence that has recently come to light has come to light that taking high doses of vitamin E supplements might increase the risk of death from “all causes,” though a separate study said there was no increase towards mortality for women who supplemented vitamin E on a daily basis. However, these results are often criticized by experts who said that they are based on recalculations of results from earlier studies of mixed quality and with variable results. However, it is still currently the best evidence available and as it stands everybody should take caution with taking vitamin E.

It is considered to be safe to take vitamin E supplements for a short period of time, only up to the recommended upper intake level. However, vitamin E has the potential of being unsafe when doses are taken orally at levels exceeding that of which is recommended. The RDA obtained through food consumption is generally thought to be both safe and beneficial.

Skin Reactions

Contact dermatitis and other kinds of skin reactions have previously been reported after using topical vitamin E preparations, including deodorants that have vitamin E in them or ointments. Rarely, it has been shown that vitamin E supplements can cause diarrhea, abdominal pain, diarrhea, nausea, or symptoms similar to that of influenza. There also seems to be an increased risk of developing necrotizing enterocolitis when taking a large dose of vitamin E.

In rare cases, there has been associations between the supplementation of vitamin E and gonadal dysfunction, as well as diminished kidney function.

Overdosing

Taking a high dosage of vitamin E on a regular basis is also believed to increase the risk of bleeding, and this is because the vitamin inhibits platelet aggregation and there is the antagonism of clotting factors dependent on vitamin K, especially with those who are deficient in the vitamin. Also associated with vitamin E supplementation, though rare, are fatigue, headache, dizziness, blurred vision and weakness.

People who suffer from retinitis pigmentosa should not consider taking vitamin E orally because it does not seem to slow down the decline of vision, and it actually seems to be associated with losing visual activity on a more rapid basis. This theory, however, has been questioned.

Pregnancy and Breastfeeding

There are numerous prenatal vitamins that are known to have small levels of vitamin E in them. It may be preferred to take natural kinds of vitamin E rather than the forms that come synthetically.

It is not recommended to take more vitamin E than the level of Recommended Dietary Allowance states that otherwise healthy pregnant women should have. Outside of this recommendation, there is currently no sufficient evidence that shows the safety levels of taking a higher dosage of vitamin E, whether injected, topical or oral, throughout the duration of breastfeeding and pregnancy. Therefore, it is not recommended to exceed such recommended dosages.
